JOSIAH GRAY, OF CHICAGO, ILLINOIS, ASSIGNOB TO HIMSELF, TESLEY HOLLENBACK, CONNELL B. SHEFLER, AND JACOB B. REED, ALL OF SAME PLACE.

RAILROAD-FROG.

SPECIFICATION forming part of Letters Patent No. 303,929, dated August 19, 1884.

Application filed January 28, 188i.

To all whom it may concern:

Be it known that I, .IosIAH GRAY, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in RailroadFrogs, and I do hereby declare that the following is afull,

clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in whiel1 Figure l is a top view showing my invention applied .in a frog. Fig. 2 is a horizontal section taken through the plane of the rails in the line indicated by .t .r on Fig. Fig. 3 is a verl-ical transverse section through Figs. l and 2, taken in the plane indicated by dotted line y 1/ This invention relates especially to what are denominated frogs77 where main-track and siding rails are used; and my object is not only to guard against the contraction ot' the siding or tnrn-out rails, but to secure the same against spreading; in other words, to keep the frog and the sections of rail which are attached to it intact.

My invention. has especial relation to a bridle and its attachments, which were secured to me by Letters Patent numbered 270,544.

The following description, when taken in connection with the annexed drawings, will enable others skilled in the art to fully understand my invention.

A designates the well-known frog which is used with rai1road-rails, and B B designate the siding or guide rails, which are rigidly attached to the frog A, in a manner which I will hereinafter explain. I show at the contracted port-ion in front of the frog that the rails B B are rigidly connected together. Near lthe point of the frog I'show that the rails B B are rigidly connected to it, and at or near the junction of thc rail-frog sections I also show that the frog 'is rigidly secured to the rails B B. It will thus be seen that I employ three independent connect-ions in my frog, which I now describe, each one of which is constructed with a buckle, C. The base of the frog-section proper is recessed into the base-flanges of theside rails, B B,as indicated in the drawings.

D designates an intermediate block, which (No model.)

. is preferably grooved on top to prevent interference with the car-wheel, and which is constructed to fit snugly the iiange, web, and base of the rails. This block may be made of steel or of other metal. Its sides may be adapted to fit the frog proper at its point, and it may be adapted to iit the rails B B at the angles thereof.

Each buckle C consists"I of a base portion, with upturned lips a a, which are perforated, as shown in Fig. 3, for the purpose of receiving a through-bolt, G, which is also a tie-bolt.

Between the upturned lips of each buckle and the outside faces of the turn-outorswitchrails B B of the frog are blocks E E, which are adapted to lit the outside faces of said rails. These blocks, like the intermediate blocks above described, are perforated, and the rails B B and thc webs of the frog arealso perforated to receive the bolt G, on one end of whicha nut, g, is applied for locking the three main points composing my frog together.

It is obvious that the nuts g may have applied to them locking devices, which will prevent them from turning loose.

It will be seen from what I have above described that I use binders, ties, or buckles G, with external and internal blocksadapted to fitthe different sections composing the frog, and through-bolts which positively prevent the spreading of the rails of the frog. In other words, I solidly connect the three parts A B B together.

It is obvious that I may apply my invention to frogs at any angle to a square crossing or a square-track crossing.

Having described my invention, I claim- The combination, with a railroad-frog, ot the intermediate and external blocks, the buckles having upturned ends, and the bolts passed through said upturned ends, through said blocks, and through the webs of the rails, substantially as described. p

In testimony that I clai 1n the foregoing as my own I affix my signature in presence of two witnesses.
